Description

Method and device for determining semi-persistent resources and communication equipment

Technical Field

The present disclosure relates to the field of mobile communications technologies, and in particular, to a method, an apparatus, and a communication device for determining a semi-persistent resource.

Background

In order to support faster data management in a 5G system, semi-Persistent resources are provided for uplink and downlink data, such as Configured Grant (CG) resources for uplink data transmission and Semi-Persistent Scheduling (SPS) resources for downlink data transmission.

In the related art, for CG resources, the resource cycle that the network can configure includes: 2 Orthogonal Frequency Division Multiplexing (OFDM) symbols, 6 OFDM symbols, 7 OFDM symbols, 14 OFDM symbols, n times of 12 OFDM symbols, and n times of 14 OFDM symbols, where n is a positive integer. For SPS resources, the resource period that the network may configure includes: 10 milliseconds (ms), 20ms,32ms,40ms,64ms,80ms,128ms,160ms,320ms, and 640ms.

In order to reduce the sending quantity of the scheduling signaling and reduce the scheduling delay generated by receiving and processing the scheduling signaling, the network side configures a semi-persistent resource cycle for the uplink and downlink services. However, when the allocated resource period does not match the arrival time interval of the traffic, additional data transmission delay is generated.

Detailed Description

Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.

In a communication network, when a network device configures a CG Resource, a Radio Resource Control (RRC) message may provide a period of an uplink Resource and a specific allocation of an uplink time-frequency Resource to a User Equipment (UE), and the UE directly transmits uplink data using the configured uplink Resource after receiving the configuration. Or, when the SPS resource is configured, the network device first configures a period of an uplink resource through an RRC message, and then controls signaling activation and indicates specific allocation of an uplink time-frequency resource through a Physical Downlink Control Channel (PDCCH for short), and the corresponding UE needs to use the configured uplink resource to send uplink data after the PDCCH controls the signaling to activate the uplink resource configuration.

The disclosure provides a method for determining semi-persistent resources, which aims at solving the problem that additional data transmission delay is brought when a resource cycle of the semi-persistent resources configured by a network device is not matched with an arrival time interval of service data to be performed in the related art. The network configures the appointed resource period for the semi-persistent resource to meet the service requirement as much as possible, thereby reducing the transmission delay of service data and improving the quality and performance of the service.

In the present disclosure, the semi-persistent resource may be a CG resource or an SPS resource, which is not limited in the present disclosure. The method, the apparatus, and the communication device for determining semi-persistent resources according to the embodiments of the present disclosure are described in detail below with reference to various embodiments.

Fig. 1 is a flowchart illustrating a method for determining semi-persistent resources according to an embodiment of the present disclosure. The method may be performed by a network device. As shown in fig. 1, the method for determining semi-persistent resources includes the following steps:

step 101, sending an indication message to a user equipment UE, wherein a specified resource period of a semi-persistent resource for service data included in the indication message is different from each default configurable resource period of the semi-persistent resource.

The service data in the present disclosure may be service data supported by any network device and UE, for example, the service data may be video data, audio data, and the like, which is not limited in the present disclosure.

Optionally, the specified resource period may be determined by the network device according to a protocol specification, or may also be determined according to a current service data requirement.

In addition, the indication message may be an RRC message, or may also be a PDCCH control signaling, which is not limited in this disclosure.

It will be appreciated that the default configurable resource period is different for different semi-persistent resources. According to the specifications of the communication protocol released by the existing 3GPP organization, for the CG resource, the default configurable resource period may be 2 OFDM symbols, 6 OFDM symbols, 7 OFDM symbols, 14 OFDM symbols, n times of 12 OFDM symbols and n times of 14 OFDM symbols, where n is a positive integer. For SPS resources, the default configurable resource periodicity may be: 10ms,20ms,32ms,40ms,64ms,80ms,128ms,160ms,320ms, and 640ms. According to the embodiment of the disclosure, on the basis of the default configurable resource periods, other configurable resource periods can be flexibly added so as to be suitable for scheduling of a novel service proposed in the 5G standard evolution process.

Optionally, in this disclosure, when determining that the arrival time interval of the service data is different from each default configurable resource period, the network device may determine the specified resource period according to the arrival time interval of the service data.

For example, augmented Reality (AR) or Virtual Reality (VR) traffic may provide video streaming services to users. Typical video frame rates are 30 or 60 frames per second, i.e. the video frame arrival interval is 33.33ms or 16.66ms, which is different from the default configurable resource period of the semi-persistent resource (2 OFDM, 6 OFDM, 10ms,20ms, etc.). Therefore, in the present disclosure, the network device may determine a current specified resource period of the semi-persistent resource according to the arrival time interval of the video service, and send the specified resource period to the UE, so that uplink and downlink data transmission may be performed with the UE based on the specified resource period.

Optionally, the specified resource period may include different contents as required, for example, the specified resource period may include a first period value, where the first period value may be a millisecond value or an OFDM symbol number.

Optionally, the specified resource period may further include a combination of a first period value and a second period value, where the first period value may be a millisecond value or a number of symbols, the second period value may also be a millisecond value or a number of symbols, and the like, which is not limited by the disclosure.

To support a wider application scenario, various SubCarrier Spacing (SCS) may be configured in the wireless communication system. As shown in table 1 below, different SCS and Cyclic prefix (CP for short) correspond to different resource allocation information:

table 1 resource allocation information corresponding to different SCS' s

It is understood that each element and each corresponding relationship in table 1 exist independently; these elements, correspondences, are illustratively listed in the same table, but do not represent that all of the elements, correspondences, in the table must coexist according to the representation in table 1. Wherein the value of each element and each correspondence is independent of any other element value or correspondence in table 1. Therefore, as can be understood by those skilled in the art, the value of each element and each corresponding relationship in table 1 are all independent embodiments.

In this disclosure, when determining the designated resource period, the network device may determine the designated resource period under each SCS according to the resource allocation information corresponding to different SCS, that is, determine the number of symbols and/or the millisecond value contained in the designated resource period under each SCS.

The method for determining the semi-persistent resource of the embodiment of the disclosure sets the designated resource period for the semi-persistent resource, and performs data transmission with the UE based on the resource period matched as much as possible with the arrival time interval of the service data to be performed, thereby reducing the transmission delay of the service data as much as possible and improving the quality and performance of the service.

Fig. 1A is a flowchart illustrating another method for determining semi-persistent resources according to an embodiment of the disclosure. The method may be performed by a network device. As shown in fig. 1A, the method for determining semi-persistent resources includes the following steps:

step 101a, determining a specified resource period of a semi-persistent resource for first service data based on a service type of the first service data.

In this disclosure, the network device may first determine, based on the service type of the first service data, a frame interval of the first service data or a time interval of the service data reaching the UE, and then determine a specified resource period of the semi-persistent resource for the first service data.

For example, when the network device has video service data to be transmitted, the network device may first determine a frame interval of the video service data or a time interval of arrival of the video service data at the UE, and then determine a specified resource period of a semi-persistent resource for the video service data based on the frame interval of the video service data or the time interval of arrival of the video service data at the UE. For example, as described below, the specified resource period may be configured to minimize the delay in transmitting the video traffic data or to eliminate the delay that may result from a mismatch between the configurable resource period specified in the existing communication protocol and the transmission characteristics of the video traffic data.

In one implementation, the specified resource period of the semi-persistent resource may be configured to be close to or equal to the frame interval or arrival time interval of the video traffic data, thereby ensuring the transmission quality of the video data transmission.

Step 102, sending an indication message to the user equipment UE, where the indication message includes a specified resource period of the semi-persistent resource for the first service data.

Further, the network device may send indication information to the user equipment, where the indication information carries the specified resource period of the semi-persistent resource for the service data.

Alternatively, the specified resource period may be different from the configurable resource period specified in the existing communication protocol. For example, a configurable resource period for CG resources is 2 OFDM symbols, 6 OFDM symbols, 7 OFDM symbols, 14 OFDM symbols, n times 12 OFDM symbols and n times 14 OFDM symbols, where n is a positive integer; or configurable resource period for SPS resources: 10ms,20ms,32ms,40ms,64ms,80ms,128ms,160ms,320ms and 640ms.

In the method for determining semi-persistent resources according to the embodiment of the present disclosure, a network device first determines a specified resource period of the semi-persistent resources for service data based on the type of the service data, and indicates the specified resource period to a UE, so as to perform data transmission with the UE based on the resource period matched with the type of the service data to be performed, thereby reducing the transmission delay of the service data as much as possible, and improving the quality and performance of the service.

Fig. 2 is a flowchart illustrating another method for determining semi-persistent resources according to an embodiment of the present disclosure. The method may be performed by a network device. As shown in fig. 2, the method for determining semi-persistent resources includes the following steps:

step 201, in response to that the arrival time interval of the service data is different from each default configurable resource period, determining a millisecond value m corresponding to a first period value included in a resource period specified under each SCS, to be a duration value corresponding to one default configurable resource period smaller than the arrival time interval of the service data.

Wherein m is a positive integer.

Optionally, when the first period value is determined, if a plurality of default configurable resource periods are all smaller than the arrival time interval of the service data, any one of the default configurable resource periods may be selected from the plurality of default configurable resource periods, or one of the default configurable resource periods with the smallest difference with the arrival time interval of the service data may also be selected.

For example, if the inter-arrival time of the traffic data is 16.66ms, then for the SCS corresponding to 15kHZ, when determining the specified resource period corresponding to the SPS, the default configurable period value smaller than 16.66ms is 10ms, so the first period value may be determined to be 10ms.

Alternatively, if the inter-arrival time of the traffic data is 33.33ms, then the default configurable period value less than 33.33ms for the SCS corresponding to 15kHZ is 10ms,20ms, and 32ms when determining the specified resource period corresponding to the SPS, and therefore, the first period value may be determined to be 10ms,20ms, or 32ms, or, since the difference between 32ms and 33.33ms is minimum, the first period value may be determined to be 32ms.

In step 202, a first difference between the arrival time interval of the traffic data and m is determined.

Step 203, determining the number of symbols corresponding to the second period value included in the resource period specified by each SCS according to the first difference value and the time length per symbol corresponding to each SCS.

Alternatively, the number of symbols corresponding to the second cycle included in the resource cycle specified by each SCS may be determined by rounding the quotient of the first difference value and the symbol duration at each SCS.

The rounding in this embodiment may be rounding down, rounding up, or rounding up.

For example, the time interval of arrival of the traffic data is 16.66ms, and the first period value included in the specified resource for SCS corresponding to 15kHZ is 10ms. At this time, the first difference is 6.66ms. The quotient of the first difference value and the duration per symbol (0.0714 ms) for the 15kHZ SCS is 93.277, with 93.277 rounded to a value 93, so that the number of symbols for the second period value in the designated resource period for the 15kHZ SCS is 93.

As another example, the time interval of arrival of the traffic data is 16.66ms, and the first period value included in the specified resource for SCS corresponding to 30kHZ is 10ms. At this time, the first difference is 6.66ms. The quotient of the first difference value and the duration per symbol (0.0357 ms) for the 30kHZ SCS is 186.555, and 186.555 is rounded to a rounded value of 187, so the number of symbols for the second period value in the given resource period for the 30kHZ SCS is 187.

For the services with data arrival time intervals of 16.66ms (the first period value is 10 ms) and 33.33ms (the first period value is 32 ms), rounding up the quotient of the first difference value and the symbol duration at each SCS, it can be determined that the second period value in the specified resource period at each SCS can be configured with the following values as shown in table 2 below:

TABLE 2

It is understood that each element and each corresponding relationship in table 2 exist independently; these elements, correspondences, are exemplarily listed in the same table, but do not represent that all elements, correspondences, in the table must coexist according to the representation in table 2. Wherein the value of each element and each correspondence is independent of any other element value or correspondence in table 2. Therefore, as can be understood by those skilled in the art, the value of each element and each corresponding relationship in table 2 are independent embodiments.

It should be noted that, the quotient of the first difference value and the symbol duration under each SCS may be determined as the second period value in the resource period specified under each SCS by using a rounded-down value or a rounded-up value, which is not limited in this disclosure.

Optionally, as can be seen from table 1, the time length per symbol, the time length per time slot, and the like corresponding to each SCS have a certain multiple relationship, and in the present disclosure, any SCS may also be determined as the designated SCS, so that after the designated resource period under the designated SCS is determined, the designated resource period under each SCS may be determined based on the designated resource period under the designated SCS.

That is, in the present disclosure, the first difference value and the rounded value obtained by dividing the time length per symbol under the designated SCS may be multiplied by the ratio of the number of time slots per frame under each SCS to the number of time slots per frame under the designated SCS, so as to determine the number of symbols corresponding to the second period included in the resource period designated under each SCS.

For example, for a service with a service data arrival time interval of 16.66ms, the above analysis shows that the number of symbols corresponding to the second period value is 93 for SCS (slot number per frame is 10) with 15 kHZ. If the 15kHZ SCS is the designated SCS, then the number of symbols corresponding to the second cycle included in the designated resource cycle under the 30kHZ SCS (slot per frame number of 20) is: 93 × 20/10) =186.

In addition, for the extended CP, since the number of symbols per slot is different in the case that the duration per slot is the same compared to the conventional CP, the specified resource period under the extended CP can be calculated in any manner of calculating the specified resource period according to the present disclosure.

For example, if 15kHZ SCS is the designated resource period, then in the case of a traffic with a data inter-arrival time of 16.66ms is determined, the first period value is 10ms and the second period value is 93 symbols in the designated resource period under 15kHZ SCS, the first period value is 10ms and the second period value is 93 x 2, where 2 is the ratio of the number of slots per frame of 30kHZ SCS to the number of slots per frame of 30kHZ SCS. By analogy, the specified resource period under each SCS can be determined.

For the services with data arrival time intervals of 16.66ms (the first period value is 10ms, the second period value is 6 ms) and 33.33ms (the first period value is 32ms, the second period value is 1 ms), in case that 15kHZ SCS is a designated SCS, it can be determined that the configurable values of the second period value in the designated resource period under each SCS can be as shown in table 3 below according to the relationship between the number of slots per frame between different SCS:

TABLE 3

It is understood that each element and each corresponding relationship in table 3 exist independently; these elements, correspondences, are exemplarily listed in the same table, but do not represent that all elements, correspondences, in the table must coexist according to the representation in table 3. Where the value of each element and each correspondence is independent of any other element value or correspondence in table 3. Therefore, as can be understood by those skilled in the art, the value of each element and each corresponding relationship in table 3 are all independent embodiments.

It should be noted that, when calculating the specified resource period corresponding to the SPS resource or the CG resource under each SCS, the method in any embodiment of the present disclosure may be adopted as needed, and the present disclosure does not limit this.

Step 204, sending an indication message to the UE, where the indication message includes a specified resource period corresponding to the half-scheduling resource for the service data.

The type or content of the indication message may refer to the detailed description of any embodiment, which is not repeated herein.

In the method for determining semi-persistent resources according to the embodiment of the present disclosure, when it is determined that the arrival time interval of the service data is different from each default configurable resource period, the network device may indicate the specified resource period matched with the arrival time interval of the service data to the UE, so as to perform data communication with the UE based on the specified resource period, thereby reducing the communication delay of the service data as much as possible, and improving the quality and performance of the service.

Fig. 3 is a flowchart illustrating another method for determining semi-persistent resources according to an embodiment of the present disclosure. The method may be performed by a network device. As shown in fig. 3, the method for determining semi-persistent resources includes the following steps:

step 301, in response to that the arrival time interval of the service data is different from each default configurable resource period, determining a millisecond value n corresponding to a first period value included in a resource period specified under each SCS according to the quotient S of the arrival time interval of the service data and the time length per time slot corresponding to the specified SCS.

Where n is a positive integer, the designated SCS may be selected as needed, for example, an SCS with a duration of 1ms per time slot is selected.

Optionally, the millisecond value n corresponding to the first period value may be determined according to the magnitude of the quotient S or a relationship with each default configurable period.

For example, the integer part of S is determined as the millisecond value n corresponding to the first period value included in the resource period specified under each SCS.

For example, the time interval of arrival of the service data is 16.66ms, the SCS is designated as 15kHZ SCS, the corresponding time duration per slot is 1ms, and the quotient S is 16.66. Then 16 may be determined as the millisecond value n corresponding to the first period value contained within the resource period specified under SCS at 15 kHZ.

Alternatively, the maximum multiple value of the first specified value included in S may be determined as the millisecond value n corresponding to the first period value included in the resource period specified under each SCS.

The first designated value may be a value agreed by a protocol, or a value configured by a network, such as 2, 5, or 10, and the like, which is not limited by the present disclosure.

For example, the first specified value is 5, and for a service with a service data arrival time interval of 16.66ms, since the SCS lower quotient S of 15kHZ is 16.66, 15 (the maximum multiple of 5) may be determined as the millisecond value n corresponding to the first period value included in the resource period specified under the SCS of 15 kHZ.

Alternatively, the duration value corresponding to a default configurable resource period smaller than S may also be determined as the millisecond value n corresponding to the first period value included in the resource period specified under each SCS.

Optionally, when the first period value is determined, if a plurality of default configurable resource periods are all smaller than S, any one of the default configurable resource periods may be selected from the plurality of default configurable resource periods, or one of the default configurable resource periods having the smallest difference with S may also be selected.

For example, if the time interval of arrival of the traffic data is 16.66ms, then the SCS corresponding to 15kHZ may determine the first period value to be 10ms when determining the specified resource period corresponding to the SPS, since the default configurable period value smaller than S (16.66) is 10ms.

Alternatively, if the inter-arrival time of the traffic data is 33.33ms, then the default configurable period values smaller than S (33.33) for the SCS corresponding to 15kHZ are 10ms,20ms and 32ms when determining the specified resource period corresponding to the SPS, and the difference between 32ms and 33.33 is the minimum, then it can be determined that the first period value can be 32ms.

Step 302, a second difference between the arrival time interval of the traffic data and n is determined.

Step 303, determining the number of symbols corresponding to the second period value included in the resource period specified by each SCS according to the second difference value and the time length of each symbol corresponding to each SCS.

In this embodiment, a specific manner of determining the number of symbols corresponding to the second period value included in the resource period specified by each SCS according to the second difference and the time length of each symbol corresponding to each SCS may refer to the detailed description of any other embodiment, and is not described herein again.

Step 304, sending an indication message to the UE, where the indication message includes a specified resource period corresponding to the half-scheduled resource for the service data.

Fig. 4 is a flowchart illustrating another method for determining semi-persistent resources according to an embodiment of the present disclosure. The method may be performed by a network device. As shown in fig. 4, the method for determining semi-persistent resources includes the following steps:

step 401, in response to that the arrival time interval of the service data is different from each default configurable resource period, determining a millisecond value o corresponding to a first period value included in a resource period specified under each SCS, to be a duration value corresponding to one default configurable resource period smaller than the arrival time interval of the service data.

In this embodiment, the specific process of determining the first period value included in the resource period specified by each SCS may refer to the detailed description of any other embodiment, and is not repeated herein.

Wherein o is a positive integer.

Step 402, a third difference between the arrival time interval of the traffic data and o is determined.

Step 403, determine the second cycle value contained in the resource cycle specified by each SCS as the millisecond value k corresponding to the second cycle value, which is the quotient of the third difference value and the time length per time slot corresponding to each SCS.

Wherein k is a positive integer.

Optionally, the quotient of the third difference value and the time length per time slot corresponding to each SCS may be rounded down to determine the millisecond value k corresponding to the second period value included in the resource period specified under each SCS.

For example, for a service with a service data arrival time interval of 16.66ms, if the ms value n corresponding to the first period value included in the resource period specified in the SCS of 15kHZ (the time duration per slot is 1 ms) is 10, the third difference value is 6.66ms. The quotient of the third difference of 6.66ms and 1ms per slot duration is 6.66, which makes it possible to determine that the millisecond value corresponding to the second period value included in the resource period specified under the SCS of 15kHZ is 6.

Similarly, for a service with a service data arrival time interval of 33.33ms, the ms value n corresponding to the first period value included in the specified resource period at the SCS of 30kHZ (duration per slot is 0.5 ms) is 32, and the third difference value is 1.33ms. The quotient of the third difference value of 1.33ms and the time duration per time slot of 0.5ms is 2.66, so that it can be determined that the millisecond value corresponding to the second period value included in the resource period designated under SCS of 30kHZ is 2 × 0.5ms.

In step 404, a fourth difference between the third difference and k is determined.

Step 405, determining the number of symbols corresponding to the third period value included in the specified resource period under each SCS according to the fourth difference value and the time length per symbol corresponding to each SCS.

Optionally, a rounded value obtained by dividing the fourth difference by the time length per symbol corresponding to each SCS may be determined as the number of symbols corresponding to the third period included in the resource period specified by each SCS.

The number of symbols corresponding to the third period included in the resource period specified by each SCS may be determined by rounding down, rounding up, or rounding up.

For example, the time interval of arrival of the traffic data is 16.66ms, and the first period value and the second period value included in the specified resource for SCS corresponding to 15kHZ are 10ms and 6ms, respectively. At this time, the fourth difference is 0.66ms. The quotient of the fourth difference value and the time duration per symbol (0.0714 ms) for the 15kHZ SCS is 9.243,9.243 rounded up to a value of 10, and thus the number of symbols for the third period value in the assigned resource period for the 15kHZ SCS is 10.

As another example, the time interval between the arrival of the traffic data is 16.66ms, and the first period value and the second period value included in the specified resource for SCS corresponding to 30kHZ are 10ms and 6ms, respectively. At this time, the fourth difference is 0.66ms. The quotient of the fourth difference value and the time duration per symbol (0.0357 ms) for the 30kHZ SCS is 18.49, and 18.49 is rounded up to a value of 19, so that the number of symbols for the third period value in the assigned resource period for the 30kHZ SCS is 19.

For the services with data arrival time intervals of 16.66ms (the first period value is 10ms, the second period value is 6 ms) and 33.33ms (the first period value is 32ms, the second period value is 1 ms), the fourth difference value is rounded by the quotient of the symbol duration at each SCS, and it can be determined that the configurable value of the third period value in the resource period specified under each SCS can be as shown in table 4 below:

TABLE 4

It is understood that each element and each corresponding relationship in table 4 exist independently; these elements, correspondences, are exemplarily listed in the same table, but do not represent that all elements, correspondences in the table must coexist according to what is shown in table 4. Wherein the value of each element and each correspondence is independent of any other element value or correspondence in table 4. Therefore, as can be understood by those skilled in the art, the value of each element and each corresponding relationship in table 4 are independent embodiments.

It should be noted that, the quotient of the fourth difference value and the symbol duration under each SCS may be determined as the second period value in the resource period specified under each SCS by using a rounded-down value or a rounded-up value, which is not limited in this disclosure.

That is, in the present disclosure, the quotient of the fourth difference value and the time length per symbol corresponding to the specified SCS may be multiplied by the ratio of the number of time slots per frame under each SCS to the number of time slots per frame under the specified SCS, so as to determine the number of symbols corresponding to the third period included in the resource period specified under each SCS.

For example, if 15kHZ SCS (slot per frame number of 10) is the designated resource period, then in the case of a traffic with data arrival time interval of 16.66ms, the first period value is 10ms, the second period value is 6ms, and the third period value is 10 symbols (9.243 rounded up) in the designated resource period under 15kHZ SCS, the first period value is 10ms, the second period value is 6ms, and the third period value is 10 x 2, where 2 is the ratio of the slot per frame number of 30kHZ SCS to the slot per frame number of 15kHZ SCS. By analogy, the specified resource period under each SCS can be determined.

For the services with data arrival time intervals of 16.66ms (the first period value is 10ms, the second period value is 6 ms) and 33.33ms (the first period value is 32ms, the second period value is 1 ms), in the case that 15kHZ SCS is a designated SCS, it can be determined that the configurable values of the third period value in the designated resource period under each SCS can be as shown in table 5 below according to the relationship between the number of slots per frame among different SCS:

TABLE 5

It is understood that each element and each corresponding relationship in table 5 exist independently; these elements, correspondences, are exemplarily listed in the same table, but do not represent that all elements, correspondences, in the table must coexist according to the representation in table 5. Where the value of each element and each correspondence is independent of any other element value or correspondence in table 5. Therefore, as can be understood by those skilled in the art, the value of each element and each corresponding relationship in table 5 are independent embodiments.

Step 406, sending an indication message to the UE, where the indication message includes a specified resource period corresponding to the half-scheduled resource for the service data.

For the type of the indication message or the content included in the indication message, reference may be made to the detailed description of any embodiment, which is not described herein again.

Fig. 5 is a flowchart illustrating another method for determining semi-persistent resources according to an embodiment of the present disclosure. The method may be performed by a network device. As shown in fig. 5, the method for determining semi-persistent resources includes the following steps:

step 501, in response to that the arrival time interval of the service data is different from each default configurable resource period, determining a quotient S between the arrival time interval of the service data and the time length per time slot corresponding to each SCS.

Step 502, determine the product of the integer part of the quotient and the symbol number per slot corresponding to each SCS as the symbol number corresponding to the first period value contained in the resource period specified under each SCS.

For example, if the arrival time interval of the traffic data is 16.66ms, the SCS of 15khz corresponds to a duration of 1ms per slot and a symbol number of 14 per slot. Then for 15kHZ SCS, the quotient S =16.66, so that the number of symbols corresponding to the first period value contained within the resource period specified under 15kHZ SCS may be determined to be 16 × 14.

As another example, if the time interval of arrival of the service data is 16.66ms, the SCS of 30khz corresponds to a duration of 0.5ms per slot and a number of symbols per slot of 14. Then for a 30kHZ SCS, the quotient S =33.32, so that the number of symbols corresponding to the first period value contained in the resource period specified under the 30kHZ SCS can be determined to be 33 x 14.

For the services with data arrival time intervals of 16.66ms and 33.33ms, when the product of the integer part of the quotient S between the arrival time interval of the service data and the time duration per slot corresponding to each SCS and the symbol number per slot corresponding to each SCS is determined as the number of symbols corresponding to the first period value in the resource period specified under each SCS, the configurable value of the first period value under each SCS may be as shown in table 6 below:

TABLE 6

It is understood that each element and each corresponding relationship in table 6 are independent; these elements, correspondences, are illustratively listed in the same table, but do not represent that all of the elements, correspondences, in the table must coexist according to the representation in table 6. Where the value of each element and each correspondence is independent of any other element value or correspondence in table 6. Therefore, as can be understood by those skilled in the art, the value of each element and each corresponding relationship in table 6 are independent embodiments.

Step 503, determining the number of symbols corresponding to the second period value included in the specified resource period under each SCS according to the time length per symbol corresponding to each SCS in the fraction part in the quotient S.

Optionally, the fraction of the quotient S may be determined as the number of symbols corresponding to the second period value included in the specified resource period under each SCS by taking the integer value of the quotient of the symbol duration under each SCS.

For example, for the services with data arrival time intervals of 16.66ms and 33.33ms, when the quotient of the fractional part in S and the symbol duration under each SCS is rounded up to determine the number of symbols corresponding to the second period value in the resource period specified under each SCS, the second period value can be configured as shown in table 7 below.

It can be understood that each element in table 7, each corresponding relationship, is independent; these elements, correspondences, are illustratively listed in the same table, but do not represent that all of the elements, correspondences, in the table must coexist according to the representation in table 7. Wherein the value of each element and each correspondence is independent of any other element value or correspondence in table 7. Therefore, as can be understood by those skilled in the art, the value of each element and each corresponding relationship in table 7 are independent embodiments.

It should be noted that, the quotient of the fraction part in S and the symbol duration at each SCS may also be determined as a value obtained by rounding down or rounding down, and the value is determined as the value of the number of symbols corresponding to the second period value in the resource period specified at each SCS, which is not limited in this disclosure.

TABLE 7

Optionally, as can be seen from table 1, the time length per symbol, the time length per time slot, and the like corresponding to each SCS have a certain multiple relationship, and in the present disclosure, any SCS may also be determined as the designated SCS, so that after the number of symbols corresponding to the second period value in the designated resource period under the designated SCS is determined, the number of symbols corresponding to the second period value in the designated resource period under each SCS may be determined based on the number of symbols corresponding to the second period value in the designated resource period under the designated SCS.

That is, in the present disclosure, the fraction part in the quotient S and the value obtained by rounding the quotient of the symbol duration at the designated SCS may be multiplied by the ratio of the number of time slots per frame at each SCS to the number of time slots per frame at the designated SCS, so as to determine the number of symbols corresponding to the second period value included in the designated resource period at each SCS.

For example, for services with data arrival time intervals of 16.66ms and 33.33ms, in the case that 15kHZ SCS is the designated SCS, it can be determined that the second period value in the designated resource period under each SCS can be configured with the following values according to the relationship between the number of slots per frame and the different SCS, as shown in table 8 below:

TABLE 8

It is understood that each element and each corresponding relationship in table 8 are independent; these elements, correspondences, are exemplarily listed in the same table, but do not represent that all elements, correspondences, in the table must coexist according to the representation in table 8. Where the value of each element and each correspondence is independent of any other element value or correspondence in table 8. Therefore, as can be understood by those skilled in the art, the value of each element and each corresponding relationship in table 8 are all independent embodiments.

Optionally, in this disclosure, after the number of symbols corresponding to the first period value in the designated resource period under the designated SCS is determined, that is, the number of symbols corresponding to the first period value in each SCS of the designated resource period may be determined based on the number of symbols corresponding to the first period value in the designated resource period under the designated SCS.

That is, in the present disclosure, a first symbol number corresponding to a first period value and a second symbol number corresponding to a second period value included in a resource period specified by a specified SCS may be determined first; then, multiplying the first symbol number by the ratio of the number of the time slots per frame under each SCS to the number of the time slots per frame under the appointed SCS, and determining the symbol number corresponding to the first period value contained in the appointed resource period under each SCS; and multiplying the second symbol quantity by the ratio of the time slot quantity per frame under each SCS to the time slot quantity per frame under the appointed SCS, and determining the symbol quantity corresponding to the second period value contained in the appointed resource period under each SCS.

For example, for services with data arrival time intervals of 16.66ms and 33.33ms, in the case of 15kHZ SCS being the designated SCS, the configurable values for the first period value in the designated resource period under each SCS can be determined according to the relationship between the number of slots per frame and the different SCS, as shown in table 9 below:

TABLE 9

It is understood that each element and each corresponding relationship in table 9 exist independently; these elements, correspondences, are exemplarily listed in the same table, but do not represent that all elements, correspondences, in the table must coexist according to the representation in table 9. Where the value of each element and each correspondence is independent of any other element value or correspondence in table 9. Therefore, as can be understood by those skilled in the art, the value of each element and each corresponding relationship in the table 9 are independent embodiments.

Step 504, an indication message is sent to the UE, where the indication message includes a specified resource period corresponding to the half-scheduling resource for the service data.

Fig. 6 is a flowchart illustrating another method for determining semi-persistent resources according to an embodiment of the present disclosure. The method may be performed by a network device. As shown in fig. 6, the method for determining semi-persistent resources includes the following steps:

step 601, in response to that the arrival time interval of the service data is different from each default configurable resource cycle, determining a value obtained by rounding a quotient of the arrival time interval of the service data and the time length per symbol corresponding to each SCS as the number of symbols included in the specified resource cycle under each SCS.

For example, for services with data arrival time intervals of 16.66ms and 33.33ms, when the quotient of the arrival time interval of the service data and the time duration per symbol corresponding to each SCS is rounded down to determine the number of symbols in the resource period specified under each SCS, the configurable numerical value of the resource period specified under each SCS may be as shown in table 10 below:

watch 10

It is understood that each element and each corresponding relationship in table 10 are independent; these elements, correspondences, are illustratively listed in the same table, but do not represent that all of the elements, correspondences, in the table must coexist according to the representation in table 10. Wherein the value of each element and each correspondence is independent of any other element value or correspondence in table 10. Therefore, as will be understood by those skilled in the art, the values of each element and each corresponding relationship in the table 10 are independent embodiments.

It should be noted that, the quotient of the arrival time interval of the service data and the time duration per symbol corresponding to each SCS may also be rounded up or rounded down to determine the number of symbols included in the resource period specified under each SCS, which is not limited in this disclosure.

Optionally, as can be seen from table 1, the time length per symbol, the time length per time slot, and the like corresponding to each SCS have a certain multiple relationship, and in the present disclosure, any SCS may also be determined as the designated SCS, so that after the number of symbols included in the designated resource period under the designated SCS is determined, the number of symbols included in the designated resource period under each SCS may be determined based on the number of symbols included in the designated resource period under the designated SCS.

That is, in the present disclosure, the quotient of the arrival time interval of the service data and the symbol duration at the designated SCS may be further multiplied by the ratio of the number of slots per frame at each SCS to the number of slots per frame at the designated SCS, so as to determine the number of symbols included in the designated resource period at each SCS.

For example, for services with data arrival time intervals of 16.66ms and 33.33ms, in the case that 15kHZ SCS is the designated SCS, it can be determined that the number of symbols included in the designated resource period under each SCS can be as shown in table 11 below according to the relationship between the number of slots per frame among different SCS:

TABLE 11

It is understood that each element and each corresponding relationship in table 11 are independent; these elements, correspondences, are exemplarily listed in the same table, but do not represent that all elements, correspondences, in the table must coexist according to the representation in table 11. Wherein the value of each element and each correspondence is independent of any other element value or correspondence in table 11. Therefore, as can be understood by those skilled in the art, the value of each element and each corresponding relationship in the table 11 are independent embodiments.

Step 602, sending an indication message to the UE, where the indication message includes a specified resource period corresponding to the half-scheduled resource for the service data.

Fig. 7 is a flowchart illustrating another method for determining semi-persistent resources according to an embodiment of the present disclosure. The method may be performed by a UE. As shown in fig. 7, the method for determining semi-persistent resources includes the following steps:

step 701, receiving an indication message sent by a network device, where a specified resource period of a semi-persistent resource for service data included in the indication message is different from each default configurable resource period of the semi-persistent resource.

The indication message may include the number of symbols and/or the millisecond value included in the semi-persistent resource in the specified resource period under each SCS. For example, the indication message may include the number of symbols included in the specified resource period of the SPS resource at the SCS of 15kHZ, or include the millisecond value plus the number of symbols included in the specified resource period of the SPS resource at the SCS of 15kHZ, and so on, which is not limited in this disclosure.

That is, the above-mentioned designated resource period may include only a first period value, such as a millisecond value, or a number of symbols, or the designated resource period may further include: the first period value plus the second period value, such as a millisecond value plus a number of symbols, or a number of symbols plus a number of symbols, etc.

Optionally, if the specified resource period includes the first period value plus the second period value, the first period value may be a duration value corresponding to the default configurable resource period.

For example, for a service with a data inter-arrival time of 16.66ms, the specified resource period may include a first period value (10 ms) and a second period value (10 symbols) at 15kHZ, where 10ms is a default configurable resource period for SPS resources.

In this embodiment, the type of the indication message, the type of the semi-persistent resource, and the determination manner of the specified resource period may refer to detailed descriptions of other embodiments of the present disclosure, and are not described herein again.

Step 702, performing data communication with the network device based on the specified resource period.

The UE determines a designated resource period corresponding to the semi-persistent resource according to the indication message sent by the network equipment, and can use the corresponding semi-persistent resource according to the designated resource period of the configured semi-persistent resource after the semi-persistent resource is activated. For example, for the uplink CG resource, after RRC configuration, data is transmitted using the uplink resource according to a specified resource cycle of RRC configuration. Or, for the downlink SPS resource, after RRC configuration and after the PDCCH activates the resource, receiving downlink data using the downlink resource according to a specified resource period configured by RRC.

It can be understood that, in the present disclosure, the indication message received by the UE is sent by the network device according to the arrival time interval of the service data when it is determined that the arrival time interval of the service data is different from each default configurable resource period, so that the indicated specified resource period matches the arrival time interval of the service data as much as possible, so as to reduce the transmission delay of the service data.

According to the method for determining the semi-persistent resources, the UE carries out data communication with the network equipment through the specified resource period matched with the arrival time interval of the service data, so that the service data communication delay is reduced as much as possible, and the quality and the performance of the service are improved.

Fig. 8 is a flowchart illustrating another method for determining semi-persistent resources according to an embodiment of the present disclosure. The method may be performed by a UE. As shown in fig. 8, the method for determining semi-persistent resources includes the following steps:

step 801, receiving an indication message sent by the network device, where a specified resource period of a semi-persistent resource for service data included in the indication message is determined by the network device based on a service type of the first service data.

The indication message may include the number of symbols and/or the millisecond value included in the semi-persistent resource in the specified resource period under each SCS. For example, the indication message may include the number of symbols included in the specified resource period of the SPS resource under the SCS of 15kHZ, or include the millisecond value plus the number of symbols included in the specified resource period of the SPS resource under the SCS of 15kHZ, and so on, which is not limited by the disclosure.

That is, the above-mentioned specified resource period may include only a first period value, such as a millisecond value, or a number of symbols, or the specified resource period may further include: the first period value plus the second period value, such as a millisecond value plus a number of symbols, or a number of symbols plus a number of symbols, etc.

For example, for a service with a data inter-arrival time of 16.66ms, the specified resource period may include a first period value (10 ms) and a second period value (10 symbols) at 15kHZ, where 10ms is a default configurable resource period of the SPS resource.

In this disclosure, when the network device has video service data to be transmitted, the network device may first determine a frame interval of the video service data or a time interval of the video service data reaching the UE, and then determine a specified resource period of a semi-persistent resource for the video service data based on the frame interval of the video service data or the time interval of the video service data reaching the UE. For example, as described below, the specified resource period may be configured to minimize delay in transmitting the video traffic data or to eliminate delay due to a mismatch between the configurable resource period specified in the existing communication protocol and the transmission characteristics of the video traffic data.

Alternatively, the specified resource period may be different from the configurable resource period specified in existing communication protocols. For example, a configurable resource period for CG resources is 2 OFDM symbols, 6 OFDM symbols, 7 OFDM symbols, 14 OFDM symbols, n times 12 OFDM symbols and n times 14 OFDM symbols, where n is a positive integer; or configurable resource period for SPS resources: 10ms,20ms,32ms,40ms,64ms,80ms,128ms,160ms,320ms and 640ms.

Step 802, performing data communication with the network device based on the specified resource period.

The UE determines a designated resource period corresponding to the semi-persistent resource for the service data according to the indication message sent by the network device, and can use the corresponding semi-persistent resource according to the designated resource period of the configured semi-persistent resource after the semi-persistent resource is activated. For example, for the uplink CG resource, after RRC configuration, data is transmitted using the uplink resource according to a specified resource cycle of RRC configuration. Or, for the downlink SPS resource, after RRC configuration and the resource is activated by PDCCH, the downlink data is received by using the downlink resource according to the designated resource period configured by RRC.

According to the method for determining the semi-persistent resource, after the UE acquires the appointed resource period of the semi-persistent resource for the business data, which is determined by the network device according to the type of the first business data, the UE can perform data communication with the network device based on the appointed resource period, so that the communication delay of the business data is reduced as much as possible, and the quality and the performance of the business service are improved.
